“…This was in line with the finding of a previous study by Thapsamuthdechakorn et al, which reported that late gestational age was the predictor of TOLAC failure (Thapsamuthdechakorn et al, 2018). Like the results of the previous study (Familiari et al, 2020), BMI is also a predictor included in the prediction model of our study. Our study indicated that women with ≥ 3 previous vaginal have more chances of successful TOLAC.…”

: The retrospective study was conducted in the Department of Gynecology Dr. Ruth K. M. Pfau Civil Hospital Karachi, from February 2021 to February 2022, for the evaluation of factors associated with the success of TOLAC (trial of labor after cesarean delivery) and to identify variables for predicting the success of TOLAC in subjects with prior Caesarean section (CS). A total of 315 women were included in the study. They were divided into the validation cohort (n=20, 63%) and the training cohort(n=295, 93.6%). The primary endpoint was the success rate of vaginal delivery. The results showed that of 315 participants, 264 (83.8%) women had successful TOLAC and vaginal delivery, and 51 (16.1%) had ERCS. According to multivariate analysis, BMI-estimated birth weight, gestational age <41 weeks, rupture of membranes, and cervix Bishop score ≥5 was significantly associated with the success of TOLAC. Results suggest that TOLAC has a high success rate in women with a history of c-sections.

“…This differs from previous studies that found an association between a prior vaginal delivery and a successful VBAC. 6,23,[25][26][27][28] This indicates there are stronger predictors for a successful VBAC than a prior vaginal birth in our analysis. Furthermore, a weak correlation was observed between parity and a prior vaginal delivery which may account for this discrepancy.…”

Purpose: We sought to determine the success rate of VBAC and factors associated with achieving VBAC at a referral hospital in the Democratic Republic of Congo in women with a subsequent pregnancy greater than or equal to 18 months from their primary cesarean section (CS). Patients and Methods: Patients were included for participation if they had an interdelivery interval (IDI) of at least 18 months from their primary CS, accepted TOLAC, and had no contraindications. Information was collected about patients' demographics, obstetric history, and factors impacting their labor process. Descriptive analyses compared patients that had a successful VBAC and those who did not. Univariate and multivariate binary logistic regression models identified factors associated with a successful VBAC. Results: Among 231 eligible patients who attempted a VBAC, 57.6% (133) achieved VBAC. Participants had a mean age of 29 (SD 6), with the majority having a prior vaginal delivery (68.8%). VBAC was positively associated with a higher Bishop score (AOR 1.12, 95% CI 1.02, 1.23) and a spontaneous labor onset (AOR 3.06, 95% CI 1.52, 6.17). VBAC was negatively associated with a macrosomic fetus (AOR 0.21, 95% CI 0.08, 0.58). Conclusion: TOLAC results in VBAC more than half the time and is associated with a spontaneous labor onset and a higher Bishop score. Women with a macrosomic fetus were more likely to have an unsuccessful VBAC, resulting in an RCS. An optimal IDI was not enough to ensure a successful VBAC. Upon patients' arrival to the hospital, practitioners should re-evaluate their eligibility to attempt a VBAC based on their Bishop score and if they had a spontaneous labor onset to decrease the health risks of an RCS.

“…The greatest part-69.1%-of Group 5 were women with the second delivery and previous CS. The VBAC rate in this subgroup was 18.1%, even lower than the overall VBAC rate in Group 5 and much lower than the VBAC rates reported in other studies (64.0% to 74.7%) [11][12][13]. Some studies excluded women with an inter-pregnancy interval shorter than 18 months, a baby large for its gestational age, pregnancy complicated by gestational diabetes, and a previous unclassified uterine scar [11].…”

There is no surgical intervention without risk. A high rate of caesarean sections (CSs) impacts on maternal and newborn mortality and morbidity. For optimisation of the CS rate, regular monitoring is necessary. In 2015, the World Health Organization recommended the Robson classification as a global standard for assessing, monitoring, and comparing CS rates. We analysed all births in 2019 in the Riga Maternity Hospital—a secondary-level monodisciplinary perinatal care hospital in Latvia—according to the Robson classification, seeking to identify which groups make the biggest contribution to the overall CS rate. In total, 5835 women were included. The overall CS rate was 21.5%. In our study, the largest contributors to the overall CS rate were as follows: Group 5 (33.3%); Group 2 (20.8%); and Group 1 (15.6%). The results of our deeper analysis of individual groups (Group 1 and 5) from our study may help to develop targeted interventions for specific subgroups of the obstetric population, effectively reducing both the overall rate of CS and the number of unnecessary CSs performed. The CS rate reduction strategy should be based on decreasing CSs in Group 1 and encouraging VBAC, thus decreasing the number of women undergoing two or more CSs in future.
